der, and the edge ot the base of the ballad rail is dropped into position to engage-such shoulder. This shoulder therefore holds the balled rail in position. But it is desirable to. hold it more firmly and for this purpose the supplementary clip 17 is used.

This clip 17 is fastened by a pivot 20. 1t has an end portion 21 which is curved in Vplan so that it can be swung around to bear against the hase of the balled rail and vto force the same into firm engagement with the running rail 11. In the Operative position, Fig. 2, there is a double heel or backing of the balled rail at two separate points, whieh tends to resist showing. ot the rail under the lateral blows of the rolling stocl.

F or convenience of operation, the clip 1TA is made to swing both ways from its operative position. rhe bearing face of the por tion 21 is cam-shaped in bot-h direct-ions to `permit this. Fig. 2 shows, in dotted lines,y theV clip swung to the left beyond the edge of the tie. The tail end 22 is short enough to swing clear of the main clip 111. `he tail end 23 of the clip 14 extends in the operative position, beyond the tail of the clip 1T so that it may be struck with a hammer to turn the clip 1% to the posit-ion shown in dotted lines. The pivot pin 19 is offset from the 'pin 20, so that in the inoperative position of the clips they may lie in the parallel po- ,sitionsshown in dotted lines.

For the greater portion of its length, the clip lllis flatand thin, about three-siiteenths to one-fourth of an inch.

tary clip 17 is bent upward toward the end 21so that it may beswungover the'clip 111 as shown in F ig. 4 when the latter is in operative position; or when the clip 1.7 is in operative position (F ig. 2) the clip 1% may underlie it as shown in dotted lines.

rEhe invention aims to provide improved devices which are more compact than those heretofore used forextending a track and which have certain `other advantages referred to in detail hereinafter.

Fig. 1 is a perspective of the end of a mine railway extended by means of balled rails;

Fig. 2 is a plan and Fig. 3 is a side elevation of the clips on one end of a Cross tie;

Fig. 4 is a section on the line lr-4l of Fig. 2 with the parts in a different position;

Fig. 5 is an end elevation of Fig. 1.

Devices of this sort are used in mines and other locations for progressively extending tance is arrived at to permit the placing of a standard length of the ordinary running rails. The extension is provided generally by means of supplementary rails which are wheels with their flanges overhanging the undersides of the rail heads.

In Fig. 1 the regular or running rails 11 are laid on steel ties 12 and held by outer 14 pivoted thereto, so that a workman can turn these clips by knocking their tail ends sidewise with a hammer. The clips have operating ends which bear on the flanges of the rail and clamp the same on the tie. The inner clips 14 have their tailends sprung downward to snap into recesses 15 on the top of the tie7 so as to llold they clips positively in operative position. The end ties 16 carry outside clips 13 and inside clips 1l1,` the same as the regular ties, and in addition clips 17 for holding balled rails. l The two clips 14 and 1'? are so arranged alongside of each other and so designed that they can be applied to ties of the ordinary standard width and do not require the eXtra wide (and therefore extra heavy and expensive) special ties which have been required forclips of previous designs.

l A balled rail 18 is placed alongside the running rail.y lying on its side with its head in the space beneath the head of the running rail 11 and bearing against the running rail. The clip 14 has a pivot with an upwardly entending'head 19 forming a shoul- `.vorlnnan :with a hammer can readily turn the supplementary clip to one side or the` otheryand loosen.4 the main clip if necessary. 1f the ies lwhich carry the supplementary clips areto be removed and advanced to be used only at .the ends' of the next complete rThe supplemenrail "sect-ions, both clips 14 andA 17 Will'be `When it is desired to slide the balled rails,

thrown off and the ties easily removed for re lacement by standard ties 12.

en the balled rails are in position, it is desirable to hold them to proper gauge at their extended ends. Owing to the firm hold ofthe shoulder 19 and the supplementary clip 1'?` very simple tie rods can be used. Theseare shown at 24. The central portion of the rod lies in a plane near the lower edges of the bases of the balled rails 11, on the heads of which the car wheels roll. At the ends ot' the rod there are upward extensions 26 ending in hooks 27 which are dropped over the upper edges ofthe rail flanges so that the rail is tied against lateral movement in either direction. Such tie rods therefore need simply to be dropped into operative position, or lifted out of it when the rails are to be removed.

The tail of the clip 17 may be made longer so as to permit operation by striking the tail with a hammer; in which ease its end portion should be bent upward to overlie the main clip 14 so as to avoid interference therewith.

Various modifications may be made by those skilledin the art without departing from the invention as defined in the followin claims.

hat I claim is 1. The combination of a running rail clip and a` ball rail clip mounted adjacent to each other on a common support, the ball rail clip having its bearing end shaped to overlie the running rail clip.

2. The combination of a running rail clip and a ball rail clip mounted adjacent to each other on a common support, the ball rail clip having a tail portion which can be swung in the direction of the running rail clip without interference with the latter.

3. The combination of a running rail clip and a ball rail clip mounted adjacent to each other on a common support, the ball rail clip havin a tail portion which is so short that it can e swung in the direction of the running rail clip without contacting with the latter.

4. The combination with means for clamping the rear ends of balled rails against the running railsof a track and means-for tying the advanced portions of the balled rails comrising a tie rod with hooked ends open at the ottoni so that they can be applied by merely dropping the hooks over the upper edges of the rail bases. v 5t The combination with means for clamp ing the rear` ends of balled rails against the tion of the rod being located near the plane of the lower edges of said rail bases.

6. The combination of a plurality of separate devices for holding a balled rail against a running rail, said devices being mounted on a common support and adapted to engage said rail at different points in its length, and meansfor holding the extended portions of two such rails comprising a tie rod with hooks at its ends open at the bot-tom so that they can be simpl dropped over the upper edges of the rail anges into operative position.

In witness whereof, I have hereunto signed my name.
